COAL-HANDLING DEVICE;

Specification of Letters Patent.

-Applioation filed January 12.1907. Serial No. 852.049.

To all whom it may concern: I

Be it known that I, EDWARD E. BARRETT, a citizen of the United States, residing at La Grange, in the County of (look and State of Illinois, have invented a certain new and useful I in'provement in Coal-Handling Devices, of which the following is a specification.

My invention relates to conveying apparatus and particularly to apparatus for hoisting material and distributing it over a considerable area, and has for its object t0 provide new and improved arrangements and devices whereby the processes of hoisting and distributing may be carried on simultaneously.

The invention is illustrated in the accompanying drawings, wherein Figure ]-is a vertical sectional view through the elevator shaft, and Fig. 2, a vertical sectional view on line 2-2 of Fig. 1.

Like letters of reference indicate like parts in all the drawings.

The invention is shown and will be described as embodied in a coal handling plant suitable. for use on railrdads where the coal is unloaded from cars, con- I veyed'to buckets or bins and there held in readiness 1 In the drawing s, A A represent tracks upon which -the"loade d coalcars are received. Beneath these tracksaz'e the bins AA' with inclined floors A A and. feed openings A A controlled by the gates A h hinged to a stationary part of the structure as shown.

B represents the structure for the elevators, which are shown as a number of buckets working in pairs so that one of each pair will be in position to load at the bottom of the shaft while the other is dumping its contents at the top of the shaft. For example I have shown four of these buckets. I shall describe particularly the pair of buckets operating upon the left handsinle of the elevator shaft as it is shown in Fig. 1, it being fp'nderstood. that the arrangement on other side or the shaft may be in all respects similar.

These buckets are designated by lhe letters l have shown the buckets as sol f dumping buckets bar-- "ingone side pivoted to the body of the bucket and held closed-by alatch pressed by a spring U". The latch has the tripping arm which comes in contact with -.a tripper C freeing the part which forms a chute for the coal, as is shown in the upper part of Fig. 2. The buckets, it will be understood, are suitably guided in the structure B.

D D are cables attached to the drum E and extending over sheaves F, F. To the ends otthese cables are attached the buckets C, C. Thecables are secured to the drum so that one un'winds while the other wirids andare guided on the idler-s G, G.

' H represents bins or pockets covered by the shed II. In the arrangement shown the bins are on each side of the elevator structure B. They may be'provided with suitable gates and chutes H extending over the coaling tracks I J in any desired and well known manner. Over the bins H at one side of the elevator structure is a track K preferably inclined and on this track runs, a car K propelled by means-of a cable or the like K extending around an idler K and over a drum K around an idler K to another car K running upon a track K extending over the bins H- at the other side of the elevators. A cable K is attached at one end to the car K and at the other end to the car K" and runs over sheaves K K and over the rollers K. The drum K is arranged on a shaft K" turning in bearings K K. This shaft-also carries the sheave F. To insuret-he closing 'of the descending buckets I provide a spring K which may be fixed to some stationary part of the elevator structure.

It will be understood that any desired form of elevating means might be used, the particular style of dumpingbucket shown being given simply for purposes of illustration.

The cars K, K are arranged to correspond with the arrangements of the buckets (l, C. When the bucket C is loading at the bottom of the elevator shaft the car K is at the outer end of its track, while the bucket C will, of course, he at the uppercnd of the elevator shaft and the car K drawn up beneath it to receive its load. The cars K, K may be of any desired type. For example, they may be automatic dumping cars and trips can be arranged along the tracks K, K so as to cause the cars to be automatically dumped at the placesdesired.

The tracks K, K are preferably slanted away from the elevators so that the loaded car will aid in pulling the empty car back to the elevator. The cars K, K in this connection may be yery properly called distributing ears as they make it possible to distribute the matcrial handled over a very considerable area. The' tracks may, of course, run at any angle or in any direc tion from the elevator. In this way the breaking of the coal is obviated and its distribution effected by the use v person skilled in the art.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to any I have shown hinged gates used in connection with the bins A but it will be understood that any other form of gate could be used. The distributing cars are shown as running directly over the bins or receptacles for the material handled, but it will be understood that they only need to be eiiectively above the same; that is, the cars so arranged as 0 be capable of discharging into the bins or receptacles. By the use of the word over I intend to express broadly such relationship.

The use and operation of my apparatus are as follows: The coal comes in on, tracks A, is shoveled or dumped into the bins A and loaded into the buckets through the feed ates A A The bucket when loaded is drawn up to the top of the elevator shalt and, when the bucket is of the type shown, automatically dumps its load into one of the cars K or K which has been drawn up into position to receive the load by the travel of the cable around the drum K. It will be understood that in theforrn of apparatus shown the cable will be given two or three turns around the drum in order to prevcnt slipping. The bucket is then lowered and at the same 'time the car runs down the track to the place where its load is to be dumped. The car is prei'erably an automatically dumping car and a tripper may be set at any point in the track to cause the same to dump its load. This tripper has not been shown as the car and its method of dumping forms no part oi this invention. The car will continue its travel to the end of the track and then be re urned to receive another load from the bucket As one bucket descends the other, on the other side of the elevator-shaft, rises, the cars K, K also working in this alternate order. In this manner coal or such like material may be handled very economically and distributed evenlybver a wide area ii des red.
